v Be it known that. we, CLRE H. Daarna g and CHARLES F. KOPER, citizensof the;

@that they are applicahie to any system wherein 4the liquid reservoir,the amount; ofY

lvnited States, residing at Hopedale, in the count)Y of 'orccster andState of Massachut setts, have invented an improvement in tirages` ofwhich the following d 2script-ion, y

in connection with the accompanying drawings. is a specification. likeletters on the drawings representing like part-s.

The invention to be hereinafter described relates to gages forindicating the amount. of liquid in a reservoir or other receptacle.-

lt has heretofore been proposed to proride a gage or indicator connectedto a reservoir or tank to make known the height of the liquid in thereservoir or tank, and where this system has been Stationary or notsubjected to bodih` disturbance. such gages vor indicators have servedtheir purpose with ln cases, however, liable to hodily disturbance, asinautomobiles, motor boats, railroad trains, and other instances-wnite theindicator or gage 'would show the actual height or amount of liquid inthe reservoir or tank when the system was in norniai level position, ithas failed to do so when the nor mal level position of the system wasdisturbed. for instance, in tlie case ot an autonioliile going up ordown hill or on a road transversely inclined. When thus dis turbed. thegage or indicator would hereto 'fore indicate either tooniuch or toolittle liquidin the reservoir or tank and the tems heretofore employedhave heen quite" unreliable excepty when in normal level position.

rPhe aims and purposes of the present invention are to'provide'a deviceof the general character stated wierein the indicating.r means shaltaccurately note the amount. of liquid iii/.the reservoir or otherreceptacle regardless of bodily disturbance oi the res crvoir orreceptacle; and its further object. is to provide a device which shellbe simpie in construction and cfiicient in operation, ailJ of which willbest be made clear from the' following description and' ecc-fimpanyingdrawings of one form of means for carrying the invention into practicaetiilect.

For convenience of description and to make clear certain broad featuresof the invention, it is shown und described as associated with thegasolene tank of an anto mobile, uit it is to he distinctty understoodthat. tne broad features of the invention are not restricted thereto,but, on the contrary,

i liquid which is to be indicated, is subject to bodily disturbance; as,foi` instance, iiquid or ,gasolene tanks in motor boats, tanks andllquid receptacles on railroad trains, and so on; and that in certain ofits features the will hereinafter appear.

screw 17, Fig. 3.

which by suction draws charges of gasolene larged portion 24 from whichextends the through the tube 7 to be exploded in the engine cylinders,as usual. A screen of wire gauze 8 is fitted in the chambei 6 to preventany dirt being carried by the gasolene to the carburetor or engine. l

Screw threaded to the ybottom portion of the outlet 5 is a cap 9 havinga perforation through which extends the upper portion of the tube 10,said tube 10 being preferably secured in place by. screw threadconnection with the cap 9, as indicated, and havin@r a side inlet 11which may extend into the 'wire screen -or cage 8, if desired.

It will be noted that the opening into the' tube 10 is disposed at theside thereof remote from 'the entrance to the tube 7', the

effect of which is to nullify toa lar e extent'- at least any disturbinginfiuence o the engine suction upon the column of gasoline :xtendinginto the tube 10 andl to the indicator, as will more fully appear.Obviously, the tank 2, its outlet and other adjacent parts may be of anygeneral form and arrangement; and the position of tlie tube 10 and itsentrance 11 may be variously changed, the essential being that disturb-vance of the liquid in tube 10 and the column extending to the indicatorby the engine suction be avoided.

IJommunicating with the tube 1,0 is the` tube 12, the end of which maybelicoiivenas a whole may be identified by A., Fig. 4-Since the dashboards of automobiles or.

other supports for the indicator differ in form and thickness, thepresent invention contemplates means for securing the indicator to itssupport regardless of variations in As one means to. this tind, the stem14 is provided with screw threads and is passed through a' suitableopening'in the dash board or support.

'Secured to the end of the stein 14 is the indicator disk 15 having thehub 16 screw threaded to the end of the stem 14 and secured or locked inproper position by a set Loose on the stein 14 at the other side of thedash board or support 3 is a washer 18 which may be caused to clamp thedash board between itself and thehub 16 of the disk 15 by means of a nut19, Fig. 3; the construction beingvsucli that regardless of thethickness of the dash board or support 3 the indicator may be ,'ije'dilysecured in place.

`,j" -The disk 15 is provided with a scale 20,

Fig, 4, over 'which plays the pointer 21- ivhi'eh is secured to a rod 22extending longitudinally throu 'h the stein 14, and preferably surioundeby a sleeve 23, Fig. The stem 14 is provided with an enpart 25, Fig. 3,having a bearing 2G for the tioat rod 27 rising from a float 28, and atits .upper end the float rod is connected to a-n arm 29 secured toa rod30 extending longitudinally of the indicator supporting` stemt-14. Therods 22 and 30 are detach- 'ably connected by means of interlockingrprojections and recesses 31, as indicated in 3, the construction beingsuch that as the float 28 rises and falls it will impart to the rods 22and 3 0 movement of rotation and move the pointer 21 over the scale 2()on the face of disk 15.`

As a convenient means for maintaining the rods 22 and 30 in operativerelation arid yet permit them to be readily disengaged for purposes ofcleaning', renewal, and assembling, the disk 15 has a screw flange 32engaged bythe screw Harige 33 of a transparent face plate 34, theconstructionl being such that the plate 34 prevents longitudinalmovement of the rod 22 to the left, Fig. 3, sufficiently to cansedisengageinent of the rods 22 and 30. Likewise the `enlarged portion 24of the indicatorsupporting stem is closedby the screw cap 36,

the'inner surface of which is snflicicntly VClose to the end of the rod30 to prevent disengaging longitudinal movement with respect to rod 22.v

lF rom the construction described, it will be noted that while the plate34 and cap 3G normally prevent disengagement of the rods 22 and 30, yetsuch disengagement may be readily effected by the removal of either.

That part of the device'or system which is to contain the indicatorliquid, such as mercury or other suitable fluid, inay for the purpose ofidentification as a whole, be here? in referred to as thcindicator'chaniberfand is connected to the indicator to permithorizontal adjustment thereof for a purpose that will presently appear.As one means to this end the downwardly extending portion 25 of theindicator may be provided with a head 37 surmoiinted by a flange 38,

vthe Said head being preferably provided with :a recess 39 extendingabout it to be engaged by the end of a set screw 40, Fig. j

5, carried by a part of the indicator chainber to be described, theconstruction, regardless of details, being such that the indicatorchamber may be adjusted horizontally about the head 37 and then securedin position for a purpose to 'be presently described.

Theindicator chamber mayvary in forni, shape, and general character, buta convenient and good practical form as herein illustrated comprises theparts 41 and 42 having communication through a connection 43 and adaptedto contain the selected indicator liquid. -For the purposes ofidentiication but without limitation, the part tank or reservoir Q.

Assume that ilu lcvel of the system isclnunfed through an angle fr. as by the automobile going down hill. Thrtank will be raised relative to the indicator through the angle u; hutthc sin-tare of the lil nid therein will remain horirumtal. extending inthe plane denoted hy the line /f. Lille-wietl the part ll of theindicator chamberwill be raised relativo to the part 42 through the anlc hut the laurt'ace of the liquidin parts and t2 ltitl llo \\ill remainhorizontal in the plane g---Jt ard Sincethe horizontal length ofi column(web) and (bvb) are related one to eighteen, thel tank will be raisedleighteen times higher than the part `il is; raised higher than the part#l2 ot' thek indicator chamber; but since the lengthl ot the columns(awo) and (cub) are refl lated inverselyY as the specific gravity of thel l liquids, the increased head of gasolene in the tank caused by itsvertical movement will be automatically counterbalanced by' theincreased head 7:27 ot' mercury caused b v the rise of part 4l of theindicator, it being understood that the height ot mercury in part 4ldoes not change relative to said l part, with the result that for agiven amount l of gasolcne the float and perfor-ce the indicator remainin the same position as when il l the system is horizontal. The sametruc y whether the liquid surface in the tank bei in the sainehorizontal plane the liquid l in the indicator when thetsystem isboris-,i zontal, or at a higher level, as indicated in tig. 7, the onlydistinction being that in, the latter case there will be an initial headi m, of mercury in part 41 of the indicator chamber to counter-balancethe initial head a ot `fasolene in the tank when the system ishorizontal, and when the system is inclined through an angle ac, asbefore, the` increased head ot indicator liquid will I connterbalancethe increased head of gasolene for the reasons already described. l Fromthe construction described, it willi be noted that regardless of changein relative height of parts of the system /duc to! longitudinalinclination of the system, the l r l l l pointer will always trulydenote the amount ot' liquid in the tank. Automobiles, motor boats, andother carriers, however, are sub4 jectcd to a transverse tilt orinclination due to road or other conditions, as well as a 'ngitudinaiinclination, and the present invention ainls` to nulhfy any effect otsuch transverse tilt upon thc indicator. To this l end, as indicated inFig. 2. the vertical plane l passing-through the center of the tank is,also made to pass through the center of the parts 4l and 42 of theindicator chamber, by adjusting they indicator chamber horizontallyabout the part 25 of the indicator as hereinbelore described. Obviously,if the center ot' the tanks and parts 41 and 2i are in the sameyerticalplane. then anyl transverse tilt at right angles to said plane will haveno elfect upon the height of the liquid either in the tank or theindicatori chamber and the pointer will remain fixed l for any givenamount of liquid in the tank. l A transversel tilt of the system at anyother angle to the vertical plane passing through the center of the tankand indicator chaillber parts 4l and 42 will be compounded ot atransverse tilt at right angles to saidi jis variously inclined. ferr-mgto a horizontal leg or column of plane and a longitudinal tilt orinclination, and as the construction hereinbefore described obviates anydisturbance of the pointer due to either a transverse tilt at rightangles to the vertical plane passing through the center of the tank andparts 4l and 42 and inya longitudinal direction, it follows thatregardless of transverse or longitudinal inclination of the system, theindicator will at all times truly note the height or quantity of liquidin the tank.

While the indicator chamber is illustrated as having the parts 41 and 42connected by a horizontal leg or passageway, it is obvious that theparts of the chamber may be variously formed and that the passageway maybe otherwise than horizontal; also that the connections between theindicator chamber and tank may be variously formed and contrived withinthe true scope of the actual invention, which, so far as known, is the"ltlrst instance where liquid in a tank has' been so connected with anindicator that the latter will accurately denote the amount or height ofliquid in the tank when the system Herein, while reliquid, it is to beunderstood that distances of separation horizontally are meant and notthat the connections or legs shall be strictly horizontal, as obviouslythe conduits or passageway/s ma vary more or less to the horizontalwithin .the true scope of the invention. y

lt will be obvious, also, that the present invention while peculiarlyadapted to automobiles, motor boats, and the like for indieating at alltimes the amount ot gasolene in the tank or reservoir notwithstandingeither longitudinal or transverse inclination 1 of the s 'stemkyet it isnot restricted to this use. but is generally applicable to any Tank,reservoir, or holder ot a liquid which is sulr ject to bodilydisturl'iance .such as herein suggestcd.
